bro ...
easy... during problem just capture a video + pic...
because from my experience its compatibility issue
(my pc just change ram slot change everything)
so to make ppl believe u kena ada evidence
and easy for shopper to take ur item to RMA
since he already sent ur gc to rma.........
if same thing like this happen to me i prefer
rosakkan dulu kaw2 baru hantar warranty...sng

* sbb ni jugak la ak malas nak bukak kedai pc haha
